Post-surgical Right Ventricular Pseudoaneurysm Presenting as an Epigastric Pulsatile Mass

We report a case of right ventricular pseudoaneurysm three weeks after open mitral valve commissurotomy. Transthoracic echocardiography showed a cavity of approximately 5 x 3 cm contiguous to the right ventricular inflow, communicating with the right ventricle by a small neck. Doppler study showed the presence of systolic and diastolic flow at the site of the rupture. Pseudoaneurysm is an infrequent surgical complication involving right ventriculotomy and often increases progressively in size. The association with open mitral valve commissurotomy has not been previously reported (Iranian Heart Journal 2010; 11 (1):38-40).
